CAR- COUPLING.

Specification of Letters Patent.

Patented Apr. 8.1913.

Application filed March 14, 1912. Serial No. 683,683.

To all whom it may concern:

Be it known that I, BENJAMIN H. BUR-- NETT, a citizen of the UnitedStates, re-

siding at Columbus, in the county of Frank- 'lin and State of Ohio, haveinvented certain new and useful Im rovements in Car- Couplings, of whicht e following is a specification.

The object of this invention is to provide an improved car couplingofthe J anney type and in which the locking pin can be set forpermittingthe separation of they cars and afterward further manipulated for Iopening the knuckle'to automatic coupling on the line wm Fig. 1 showingthe locking pin supportedpart way up. Fig. 3 is a similar view on theline 2--2 showing the in down. Fig. 4. is a plan view of the l ower sideof the coupling. Fig. 5 is an elevation of the left hand side of thecoupling. Fig. 6 is a view of the left hand side In the views 10designates the draw bar which is provided with a head '10 having asuitable cavity in its forward end to receive operative parts. On thehead at the left hand side of the cavity are two perforated projections11 and 11 to receive vertically alined pivoting pins 12 and 12 oncorresponding projections on the knuckle l5.- The projections 11 and 11are spaced sufliciently apart to permit the pins 12 and 12 to becentered over and inserted into the perforations in the projections 11and 11 while the knuckle is opened -to more than normal. The lower pin11 is made long enough to project below the ear where it has secured toit a keeper 13 in such position that said pin will abut against a stop14 on the lower side of the head and prevent the knuckle from turning sofar from open position as to render it liable to be lifted off theprojections 11 and 11*.

The knuckle has an inwardly projecting tail piece l5 from the lower sideof which projects a pin 15". Pivoted at- 16 in the rear wall of thecavity of the head is a lever or kicker, so called, that has at one sidea curved arm 17 reaching behind the pin 15 and at the other an angulararm l7 reaching forwardly in proximity to the right hand side of thelocking pin. The locking pin includes a shank port-ion 18 that extendsupwardly through a vertical hole 10 in the draw head and is accessiblefor manipulation at the upper side of the head. At its lower endthelocking pin is provided with a blade-like member 18" extendingrearwardly in a plane inclined to thevertical plane of the axis of thedraw bar, and said blade has an inclined edge 18 that, when the pin israised, is adapted to act on the angular arm of the kicker and throw thearm 17 forward. A suitable opening in the lower side of the draw head isProvided, as shown, for the operation of the said blade. The locking pinis also provided with a lateral tooth 18 adapted to rest on a tooth 10on the wall of the cavity where the pin works.

In Fig. 2 the locking pin is shown as raised and supported by thesuperposition of the tooth 18 on the tooth 10. This position of the pincan be had when the knuckle is in closed position, as shown in Fig. 1and while two couplers are coupled and it is desired to separate thecars. It is obvious that in this position of the parts the knuckle canbe pulled out to open position, as shown by broken'lines Fig. 1. Ifafterseparation of the carsthe knuckle be not in proper open posit-ionfor'coupling that member can be thrown to proper open position by rais-,ing the pin to actuate the kickerthereby' causing the arm 17 to operateon the pin 15 and throw the knuckle to full open position. When theknuckle has been thus turned out the pin is lowered to rest on the tooth10, and when the open knuckle of another car enters the coupling soplaced the angular arm of the kicker by the action of the pin 10 on thearm '17, unseats the locking pin permitting it to drop to position tolock the knuckle from opening at all. The locking pin has a shoulder 10to support it in low ered position. i

What I claim is:

In a car coupling, the combination of a draw head having a suitablecavity, a knuckle having a tail to work horizontally into said cavity, alever having two arms 17 and 17 fulcrumed to swing horizontally in saidcavity,'the arm 17 to engage the tail 2Q: onnie? 1 of the knuckle, avertically and rectilineeifly i raised position to permit the opening ofthe sliding locking pin 18 having a tooth 18 I knuckle, the arm 1? 0fsai'cl lever being actuon its shank and n blade-like member 18 ated bythe tail of the knuckle to throw the at its lower end, said blade-likemember haw arm 1'? directly against the locking pin to 5 ing an inclinedeclge 18* which When raisell i'eleaee the same to knuckle lockingposition 15 acts on the arm N of said lever to throw when the knuckle isclosed.
